Abstract: Noise attenuation apparatus for fluid devices are disclosed herein. A noise attenuation apparatus includes a first plate having a plurality of first openings to reduce noise generated by a fluid flowing through a fluid device and a second plate having a plurality of second openings to reduce noise generated by the fluid. The second plate directly engages the first plate, and the first openings to at least partially align with the second openings when the first plate is in direct engagement with the second plate to define a flow passageway of the noise attenuation apparatus.

Abstract: A balanced pressure regulator includes a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway. A valve seat is disposed within the fluid passageway. A balanced plug assembly is disposed within the fluid passageway, the balanced plug assembly including a valve plug that cooperates with the valve seat to selectively open or close the fluid passageway, a retainer operatively connecting the valve plug to a valve stem, a diaphragm separating a chamber from the fluid passageway, a central balancing passage that fluidly connects the fluid passageway with the chamber, and a peripheral balancing passage that fluidly connects the fluid passageway with the chamber, the peripheral balancing passage being located between the retainer and the valve plug.

Abstract: A slam-shut safety device includes a valve body, a valve disc, a reset pin, and a guide collar. The valve disc is disposed within the valve body and shiftable along a slam-shut axis between an open position and a closed second position. The reset pin is operatively coupled to the valve disc and shiftable along the slam-shut axis relative to the valve body between an untripped position placing the valve disc in the open position and a tripped position placing the valve disc in the closed position. The guide collar includes a hollow cylindrical portion extending away from the valve disc at least partly over the reset pin and being slidably disposed in a guide bore of a slam shut body that is connected to the valve body and supporting the reset pin, thereby providing added structural integrity to the rest pin and valve disc.
Abstract translation: 一种关键的安全装置包括阀体，阀盘，复位销和导向环。 阀盘设置在阀体内，并且沿打开位置和关闭的第二位置之间的关闭轴可移动。 复位销可操作地联接到阀盘，并且在将阀盘放置在打开位置的脱扣位置和将阀盘放置在关闭位置的脱扣位置之间相对于阀体沿着冲击关闭轴线移位。 引导套环包括中空圆柱形部分，其至少部分地在复位销上方远离阀盘延伸，并且可滑动地设置在连接到阀体并支撑复位销的大闸门的引导孔中，从而提供附加的 结构完整性到其余的销和阀盘。

Abstract: A slam-shut safety device having a disc arrestor includes a valve body, a valve seat between an inlet and an outlet, and a reset pin shiftable between untripped and tripped positions. A valve disc support includes has a threaded stem and is operatively coupled to the reset pin. A valve disc fits on the stem of the support and shifts in response to movement of the valve disc support between an open position and a closed second position in which the valve disc is seated against the valve seat. A threaded nut is securable to the threaded portion of the stem of the valve disc support, and an arrestor spring is positioned on the stem of the valve disc support and is secured by the threaded nut. The arrestor spring is arranged to apply a biasing force to valve disc.
Abstract translation: 具有盘式停止器的关键安全装置包括阀体，入口和出口之间的阀座，以及在未脱扣和脱扣位置之间可移位的复位销。 阀盘支撑件包括螺纹杆，并且可操作地联接到复位销。 阀盘安装在支撑件的杆上，并响应于阀盘支撑件在打开位置和闭合的第二位置之间的移动而偏移，在该关闭的第二位置，阀盘抵靠在阀座上。 螺纹螺母可固定到阀盘支撑件的杆的螺纹部分，并且避雷器弹簧定位在阀盘支撑件的杆上并且由螺纹螺母固定。 避雷器弹簧被布置成向阀盘施加偏置力。
